Laser tricks win physics NobelLaureates include first female winner in 55 years
“First of all, you have to think it’s crazy, so that was my first thought,” said Strickland during the announcement of the prizes on 2 October
His experiments with micrometresized spheres showed that the particles were drawn to the highest-intensity region in a beam of light. This led to a way to sculpt lasers to trap, levitate and move objects. Ashkin discovered that these ‘optical tweezers’ could capture bacteria, viruses and living cells
Summary
Laureates include first female winner in 55 years. The laureates include Donna Strickland, who is the first woman to win the award in 55 years. Strickland and Mourou pioneered a way to produce the shortest, most-intense pulses of light ever created. These are used throughout science to unravel processes that previously appeared instantaneous, such as the motion of electrons within atoms. Ashkin won the prize for developing ‘optical tweezers’, beams of laser light that can grab and control microscopic objects such as viruses and cells. “First of all, you have to think it’s crazy, so that was my first thought,” said Strickland during the announcement of the prizes on 2 October. “And you do always wonder if it’s real.”
